连续箱梁弯曲问题的有限单元法

Finite Elements Analysis of Continuous Girder with Box-shape Section Cross

在文 [1 ]、[2 ]三维退化层合梁的基础上 ,引入板壳的基本假定[3] ,构造出三维退化层合板壳单元 ,分析了单箱室连续箱梁的弯曲问题。计算结果表明 ,该单元的精度和效率较高 。

Based on the 3-D deteriorate laminated beam element in documents [1]and[2],and by the assumptions in the theory of plate/shell,the 3-D deteriorate laminated plate/shell element is presented in this paper for analysis continuous girder with box-shape section cross,the results of which elucidate that the method and the element are more effectively than much of others.
